[Asterisk-Dev] The Almighty X-Lite DTMF Problem

[Peter Grace]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I tried it but it doesn't appear to do the trick..  It
seems like X-Lite doesn’t send the end bit??  Not so sure,
I'm trying to debug a few of these variables but it just
doesn’t quite add up.  The variable data, which event_end
is keyed from, is the button pressed.  It doesn't look like
a bitwise variable?  Maybe I'm showing my ignorance here. 
How can I confirm if X-Lite is in fact setting the stop
bit?

Pete,

Try this patch below...  I noticed that eStara's softphone
has the same problem as xten's softphone when it comes to
DTMF.  Seems as though Asterisk is not looking for the
"end" bit per RFC2833.  So try this fix.  It should do the
trick (at least... it fixed mine).
